What is research? vi-jai -- collect, search, karn-kon-kwa-ha-kor-moon yang-tee-toan tam-luk-vi-cha research -- scholarly or scientific investigation or inquiry scholar -- 1 a learned person 2 one who attends school or studies with a teacher

What is research scientific -- employing the methodology of science scientific method -- The totalities of principles and processes regarded as characteristic of or necessary for scientific investigation, including rules for concept formation, conduct of observations and experiments, and validation of hypotheses by observations or experiments.

Scientific method 1 Hypothesis 2 Design of experiment 3 Experiment and collect data 4 Analysis of data 5 Interpretation of results

Why research? (left for exercise)

How to do research? Curiosity Asking questions Refine questions Formulate method to get the answer – literature review – background theory Design (for synthesis problems) Experiment (for analysis problems) Analysis & Validation Interpretation

Current topics in Computing (from IEEE Computer Science Discipline) The World Wide Web and its applications Networking technologies, particularly those based on TCP/IP Graphics and multimedia Embedded systems Relational databases Interoperability

Current topics in Computing Object-oriented programming The use of sophisticated application programmer interfaces (APIs) Human-computer interaction Software safety Security and cryptography

Characteristic of graduates Knowledge Modeling Requirements Critical evaluation and testing Methods and tools Professional responsibility

Skills of graduates Design and implementation Evaluation Information management Human-computer interaction Risk assessment Tools Operation

Skills of graduates Communication Self management

Step-by-step of doing research What is your interest? Find the right teacher Work with your advisor Asking the right research question – doable in a reasonable time – do you want to publish? Do small project (or initial Design) Experiment with your project/design Work with your advisor Write paper/thesis

Examples of the research work Web A Popularity-Based Prediction Model for Web Prefetching Computer systems Simulating a $2M commercial server on a $2K PC Graphics Made-to-measure technologies for an online clothing store

Examples of the research work Software engineering Computer-mediated group support, anonymity, and the software inspection process: an empirical investigation Computer architecture Power evaluation of a handheld computer Robotics Sharing control

Examples of the research work Evolutionary computation Globally convergent algorithms for dc operating point analysis of nonlinear circuits VLSI Instruction-based system-level power evaluation of system-on-a-chip peripheral cores Mobile computing A comprehensive resource management framework for next generation wireless networks

Examples of the research work Intelligent systems Intelligent indexing of crime scene photographs Programming languages A Programming System for Children that is Designed for Usability

My own observation research is very much social activities [but a lot of time you need quite time and place to think hard.] motivation is very important [find the topic that suite your interest and work with your advisor to make it doable.] publication always takes more time than you expect. start writing a thesis is difficult but finishing one is easy.

Exercise Working at home is more comfortable. Why come to school? Many things can be self-taught why need a teacher? How much time is needed to do research? What you will get out of doing a research?

End Good luck and start talking to faculties!
